Tan 97 Degrees
Sin, Cos, Tan, Cot of an Angle
What is tan 97°?
Answer
tan 97° ≈
−8.1443
Angle in radians: 97° = 97π/180. The point of the angle is in quadrant II, where tangent is negative.
≈ — rounded to 4 decimal places. tan 97° can't be written with square roots: 97° is not a multiple of 3°.
tan 97° = tan(180° − 83°) = −tan 83° ≈ −8.1443
tan 97° = sin 97° / cos 97° ≈ −8.1443
P(cos 97°, sin 97°) ≈ (−0.1219, 0.9925)
T(1, tan 97°) ≈ (1, −8.1443) — where line OP meets the line x = 1, on the extension of the ray beyond O (dashed); T is beyond the drawing, the arrow points to it.

FAQ
What is tan 97°?
tan 97° ≈ −8.1443
Why does tan 97° have no exact value?
A trigonometric value of a whole number of degrees can be written with square roots only when the angle is a multiple of 3°. 97° is not, so no such exact form exists; the value is used as a decimal: tan 97° ≈ −8.1443.
Why does a calculator show −0.4103 for tan 97?
The calculator is in radian mode (RAD): it takes tan 97 as the tangent of 97 radians, tan 97 rad ≈ −0.4103. Switch it to degrees (DEG): tan 97° ≈ −8.1443. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
